To onliy whom it may conceru g Beit known thatwe, JAMES G.BEAT'rIE a-nd .TACoB HUETHER, residing at New York, borough of Brooklyn,

i in the county of Kings and State of New York, 'and JAMES E` MARTIN', residing at New York, borough of Manhattan, in the county of New York and State of New i l`5-tops ,1plain or embossed, glazed or unglazed, papercovers and afiixing the said covers 'to the bottoms and i in andaiXing-'the edges of the covers .to the inside ol the top edges of the box and their tops for the purpose of'covering and finishing the said edges.

The-object of the invention is, first', to simplify the 'construction and operation of machines of this character, to render the operative parts readily accessible, and

Y adapt them to perform their several operations by simple d irect and generally positive motions in horizontal lines; second, toobviate the liability' o the operator being injured While feeding the boxes to the machine;

third, to operate the devices-Which carry the box and hold and present it to the covering mechanism positively by ba single cam and retain control of the box and cover both When moving and at rest until the covered box is stripped from the device that holds it on the support and carrier during the covering operations; fourth,

to prevent lfouling of the tab-folding devices by the offsetting o f the glue pressed out by th tab-folders from y loetween'the infolded tabs and the'ends ofthe box; fifth,

to prevent the sides of the box and cover' affixed thereto from bulging or becomingdistorted by the pressure of the tab-folders and the end covering Vrollers;sixth, to 40 eject the box after the covering is completed from the -machine at the bottom or below the covering mechan- ,ism and 'thereby avoid returningy `the' covered box through the'icovering mechanism to the top of the machine and exposing` it to injury by the mechanism, or dcfacement by the offsetting of any glue that rnayadhere to the mechanism; seventl1,-tostrip or shed the covered box from the device that holds it on the support and cari'ier without 'danger' of injurinUr the same; eighth, to ohviate the liability of injuring the edges of the box when turning the edges of the cover over and down and afixing them. to the inside of the top edges oi the box; ninth, to insure al prompt, quick and jarless return of the box and 'cover support and carrier to its normal position flush with the feed table; and, finally to insure promptness in the working ofjthe machine, facilitate the Specification of Letters Patent.

work of the operator and prevent injury to the box and covering and carrying devices by the sudden reversal oll their motions and their abrupt stoppage when they return to their normal positions.

The object first mentionedis attained by lor-ating 50 the covering devices, the 4tab-folding mechanism, the edge turning mechanism, the stripping' or shedding mechanism and the ejector iu galleries, und arranging the operating mechanism that connects these parts with the driving mechanism in horizonlnl planes so 65 that the devices for*operating these several mechan- `isms in each gallery are distinct and separate from those.

which operate the mechanisms in the other galleries, this object-being further secured by operating they mechanism in the several galleries from a single. shaft .7D geared to the driving shaft. .i l

.The second object is attained by arranging' the dc.A

vice that holds the box and eoveron the support or: carrier and move the same downward to the covering 'mechanism so that the operator can feed the box. to 'l the machine by grasping it by the lop thereof and avoiding' placing the hand under the said device, and

`hold it thereon' until it rests between the sniddevice and the support or carrier, thus obvinlng the danger arising from the liability of the operators hund being` caught and crushed between the device and support and carrier.

The third object is-attained by a loom cam operai ing upon the device that holds the box and cover on the support and carrier and moves them do\vu\\'-.\rd to the 85 covering mechanism, through rack bars and pinion.- so that the support and carrier is controlled by the can; when moving and also when at rest; the box and its cover being carried by direct acting meelmnism they are presented to the successive coveringl devices at the 0 0 instant these devices are ready to operare in turning and afiixing the different parts ol the cover to the box. and their movements are arrested promptly at those points where the motions of the devicesiare at right angles to the motion of the box and cover and where consequently, if any movement of thc box and cover took place they would beinjured by these devices.

The fourth object of our invention is attained 'by arranging th'e tab-folding devices so that after moving parallel to'thc ends oi the box far enough to tuekior l0() fold inthe tabs and press and allix'them to the ends ofthe box, they are swung outward awayffi'om the box before they pass the Vedges of the tucked iu tabs and come in contact with the glue squeezed out from between the tabs and the ends of the box, whereby offsetting of the expressed or exuded glue and fouling of the tab-folders are prevented. v Y

he fifth` object of our invention-is attained by means of vertical plates alinedwith the side covering devices and extended down below the tab-'folders and 110 i the end covering devic by means-oi' which the sides of the box are supported 'and braced when the tabi'olders and end covering devices bearagainst'the ends ol the bor; in folding in and alli'xing thev tabs to the ends' ot' the box and 'turning up and allixing the ends of the cover to the infolded tabs and the ends ot the box.

The sixth object of our invention is attained by providing stripping or shedding devices located in the third and lowest gallery and in line with the extreme downward position to which the covered box descends, whereby when it arrives at this position, the strippers are advanced and engage the top edges ol the box while' Vvthe deyice that holds theI box on the support" 'and by a quick action, ejects the box'irom -thesup port. and carricrbel'ore the latter'l begins..its upward motion to return to its normal position flush with the l top ol-the feed table.

The eighth object o; our invention. isattained by making the edge turning devices mpvable horizontally to turn the edges ol' the cover overy the top edges ol the box and hold them temporarily yin that position until by rcveising the motion of the support and carrier the edge turners are caused to enter the `box and turn the edges el' the cover down parallel to the inside surface ol the box to which they are aliixed by irnparlin g pressure to both sides and ends of the box simultaneously against the resistance oi' the edge turner's within the box, between which and the presser blocks the edges of the cover are atiixed to the inside oi' the box, y

The ninth o bject of our invention is attained. by connecting the support and carrier with a piston operating in a. cylinder provided with valves so that the reversal ot the motion oi the support and carrier will be effected by the action of the air compressed in the cylinder by the action o1' the piston and the downward movement ot' the support. an'd carrier, wherebythe support and carrier is caused to bearupward against the pressure of the device by which it is lorced down, is also held stationary when the downward pressure ceases and moved upward when the device is moved upward or lifted lrom it after the box is stripped off.

The leading objects et' our invention and the means oi attaining them are set forth but manyininor but none' the less-important and valuable improvements' are incorporated inthe machine which will be pointed "out and explained when the construction and opera- (ill tion of the several parts and their relation and cor- Iinationare described in detail and in connection with the drawings.' s Y Simplicity ofconstruction by the use oi as iew and simple mechanical elements as possible to produce the. results, directness ol connection between the driving mechanism and the operative parts of the machine andas many positive' motions as possible, `have been our aim in the production of this machine and compared with other machines these results have been ob-v tained without sacrifice of efficiency.-

Iira'me of the machtne:-This isconstructed of side members A A each ot' which consists of uprights B B and a cross bar C. Each of the side members is' prelerably an integral casting. They are connected together below the driving mechanism by 'transverse rods D D and at the top by a plate E. l

F G are standards bolted or otherwise iastened to thetop E. StandardnFlis'placed at the. iront .sideo 1 the top and standard Gat about the' center.

H is a bracket fastened to the top at therear side and projected iroin the same, that has a. journal-bearing -oformed therein and fitted with a cap.

l is a` bar bolted to the rear side ol the frame that` has a l pedestal journal-bearing f-bconnected with it and which is in vertical alinement with the. 'upper journalbearing (Paf. v

A projection .l on the rontside of the standard F atthe top has arcctangular slot- -df in it in line with a similar slot -cin the top at the iront; the two slots serve as guides for 'the rack-bar hereafter referred to;

iand cap platesare litted over these slots t0 hold therack-bar inthe slots, Standard F is also provided with journal-bearings, and a shalt -jis journaled therein and carries'two rack-pinions which will be described later.

K is a feed board or table supported between the sidev frames below tlie top E andhavng itsfront'extended outward and liollowed out to partly receivothe body ol theoperator for convenience in feeding the' machine.`

The table has a central square'opcning grlarge i enough for the covers of the largest boxes to`pass through when spr .ad out flat. l

Projections .-hkh at the top and bottom, of the standard G are slotted and fitted with caps to form guide slots'mt''iffor the rack-bar that carries the boxv and cover holder which7 as shown in this instance, is a plungerand will hereafter be described more fully. Theseslots iwi/- are in line With a rectangular opening -j-' in thecenter of the top E. On top of the feed' table there are'adjustable gages -l#-Z-' to guide the operator in properly centering the cover on the box and cover support andfcarrier. v

feed table and located and spaced so as to form three galleries O lP Q, the first between the feed table andthe or L7 thesecon'd between the floors L and M and the third below-the floor M. Theboxes and the covers are carried down. through these galleries in succession and presented to the covering mechanism as they descend. These floors M' respectively have circular openings "m'wn-centere'd with the square opening in the feed table;and the edges of the openings --m--nh are provided with peripheral ridges -p.-q-respectively, that form tracks` fbr the oscillating rings or turn-tables hereafter'described.

Dri-ning mcczam'sm:-S is the driving shaftwhichis supported horizontally at the rear of the machine in journal-bearings f-Z-Qv bolted to the side frames.

frames, and near the middle line between the front and back thereof7 in` journal-bearings rl fastened to the side frames. One end of this counter-shaft carries a spur-wheel ---9- that meshes with the driving pinion -3- and the opposite end carries a cam -l0.

Y A vertical shaft U is journaled in the bracket bearing -aand the pedestal bearing -'-b This vertical shalt carries a bevel wheel -1lthat meshes with a bevel :wheel v-l 2*- on Athe counteislnxft T. The spurL wheel runs ifree onthe counter-shaft and is driven continuouslylllby the driving-pinion.' The countenshaft is designed make one revolution during which the box is completely covered and ejected from the machine and. the Vdepressing device and box and cover support land carrier are returnedto their normal or starting positionready for the feeding of another boxV and cover to the machine, and then brought to full stop automatically by mechanism which will now be d cscribed n treadle -`l3-- at the front of the machine in posi'- -tion to be controlled by the operatons foot, fitted toa rocking bar -lLl-, supported transversely of the frame and that 'carries an arm 15- i-xed thereto at the end next `to the spurfwhe'el W9". This arm has aprojee tion -rlAGLatifs upper end and one side of this projection has a vertical inclined face -l7-. The upper end of this arm is in line with a 'circumferential groove and fastened by screws. L M are floors secured to the side frames below the v.-l8-l, in a sleeve -l9- splined on the counter-shaft `rl outside of the hub -Zlof the spur wheel -9-.

In the sleeve there is a hole 20-y parallel to the shaft extending from end to end of the sleeve. A pin ld is inserted i-n the hole -20-. This pin has a reduced end --22- next to the spur wheel and its opposite end is bored out to Vform a socket-S- in which is inserted a coiled spring -24-; The pin `is held in the socket by a stud 25 dri ven through a slot 2G in the' sleeve and by a plate 27 inserted in a dove tailed groove iu the end of the sleeve behind the spring 24 y The part of pin -2l that crosses the groove -l8- of the sleeve is notched transversely as at -ZS- and the side`-29`t of this notch, which is next tothe inclined face 17- of the .projection 16- of the arm,` is inclined about parallel to the face -].7-. The pressure of the spring tends to force the reduced end 22 of pin 2l out of the hole 20 into the 'inclined holes 30 of the hub of Wheelv 9; the pin 25 which travels in the slot 26 tends to keep pin. 2l from revolving and thus keeps slot 28 in analinement with groove 18. The web of the spur-wheel is provided with a number' of holes -3.0-'which are equally d is?I tant from the center of the shaftandinline with theV end of the pin 21%. 'By the rotation of the spur wheel these'holes are brought in line with the endet the pin which will enter one or the other of the holes 'i when released and the holes come into line therewith as presently described. At the beginning of the operation of the machine the upper' end of the arm lies in i projection -lG--, bears against the inclined side -29- of the notch w2S- and thus holds the pin sheathed in the hole against the pressure the spring. When thetreadle is pressed down the arm is thrown out, thereby releasing the pin, and the spring in the socket forces the pin out of the hole against the web of the spur wheel so ythat when one of the holes nv20- comes in line with the pin it enters the hole and thus couples the spur wheel and sleevetogether so that (he sleeve and with it the CoiiuLershat are rotated by the spur wheel. When pressure s released from the treadlcthe upper end of the arm is thrown forward into the groove, As the'spunwhcel approaches the end. of on(- revolution the inclined face QQ- of the pin is brought into contact with the inclined face iT-of the pro! jection -loby the rotation of the sleeve. and bearing against the same the pin is moved back and the; reduced end withdrawn from the hole in the web of the spur-wheel, thus uncoupling the sleeve and stopl ping the rotation of vvthe counter-shaft at the complotion of the rotation of. the spur-wheel, and stopping also the operation of the machine. Thus hy pressing' the treadle the machine isstarted and is promptly stopped automatically when the counter-shaft com. pletes one revolution. I

B01' and conn-r'cmrarsx;These comprise a `plunger -34- and a vertically movable table-35jwhich are located centrally in tlfemachine. The table is aa'- ranged to be depressed vertically by the descent of the plunger from its normal position in the opening-.gf inthe feed table, down through `the galleries tothe place where; the box is ejected `from the machine and is recovered; in this example it is'rectangular and its di mensions, Vthat is7 its length andwidth must be such that it vwill enter the box to .be coveredeasily; hence,

as the machine is adapted or intended to 'cover boxes of various sizes 4there must be as many plungers or each machine-as the machine is otherwise adapted to cover.

`The thickness' of the`plunger i's less than the 'depth of the box and: its sides and endsiit squarely against the Vwalls of the box,- but not so close as 'to make it difiicult .to strip the box oii'of it after the covering is completed.

, The plunger is soeketed to receive the lower end oi a rod -,36- to which it is fastened' by means of a set-v screw. Therod --36- works through' the opening' j-in the top E'and the /guides --fi---z-v in the projections `-h'h- The upper part of the rod is formed or fitted with a rack 37.- which meshes withapinion v w38- on the sh'ait f- The vertical motion of the .520.: by which it is guided. The said slotted bar has a head plunger is produced by the, cam -10- that operates a slotted bar 39- through .which the countershatt T is passed,` the bar being held between collars -40-41- i-42f which is bent' over at right angles and coupled to' a rack-bar -43--- thatis passed through the guide slots A'--ie--d-e in the thble and the projection J' respectively and meshed with a pinion-4 4- on the end oi the shait-f-- opposite the pinion -38-.A

The cam -fldvis similar@ to a loorncan'r and the const ruction is such that it gives a rapid upward or return movement tothe plunger lwhile the downward movement is timed to harmonize with the movements of other mechanism and in places is entirely arrested to al-l low theA covering devices to perform their several operationsin coveringthe box. The cam face is formed by a flange #45- which runs between an anti-irictionl 35,

roller A64-mounted on a stud 47 and the rollers -48-49- in the-lower endsof the arms -50-51- mounted Ona stud fixed to the slotted bar, the upper' ends of-the arms being connected together by a spiral jspring -52-. By this construction both the upward and downward movement ofthe rack-bar are controlled bythe cam in part.

Turning up the sides of the coibercmd axz'ng thtm to the sidesvbf'tlie' bmx-:Underneath thev feeding table on v lopposite sides ofthepening -l-gmidway between the side frames thereare adjustable plates --'5353- v'which are connected withthe under side of the feed table by means of set screws .passed through slots in theplates and into tapped holes in the feed table.

The inner ends of these adjustable. plates are'curved,

the same 'and which is illustrated and will be fully described in connection with the description oi the mechanism for turning up the ciids oi the/covers and fastening them to the ends oi the box. Over the side covering rollers -55-55 there are fixed vplates --,-56-56 the inner edges of which are curved downward over the rollers and project-slightly'beyond the faces oi the rollers; The functionbthese plates is to scrape oli or remove any glue that may spread over the outer sides of the coverjor be squeezed out by the pres? sure-oi the rollers and thus prevent suchglu-e from reaching the rollersandl offsetting thereon. Below the side/'covering rollers there are'vertical side-supporting plates -57- 57-v` in the same vertical planes -with the faces of the-rollers and which are held in pendent po-A sition by the upper inclined ends -58-58-.be 1 ing connected with bars -54-54-- These plates extend l down below the devices that apply the ends oi the cover to the ends of the box and within the opening of floor h; The function oi these plates will be described hereafter.

. so ing in the projecting ends or tats of the sides of tlm co'vcrf-The mechanism for this purpose is` located in gallery O and will now be described in connection with Figs. 2 and?) (SheetsH-Hl). There are four. tabfolders, two'i'or each end of the box 'and those which are connected with the same operative' mechanism on one side'are marked 5 9-59- and those on the opposite side #G0- 60%. As these tab-folders and the` means by which theyare operated are precisely alike the description oi 'those on one side and the operativo' mechanism therefor will be equally applicable to those 'on the opposite side and the mechanism by whichsthcy are operated. The tab-folders consist of metal plates -Gl. The ends *G2-- that bear against the projections are convex vertically so that when they bear against 'the tabs they will tuck the same in against the ends oi the bmi withoutK liability of tearing the paper. They are oi about the same width vertically as'the depth oi the box; hence, as the machine is intended. to. cover boxes of different depths these tab-folders must be changeable to correspond tothe 4depth ofthe boxes which the machine is engagedin covering. The s hanks -63- oi the folders are bent to a. rectangular form so that they'will slip into vertical slots -Glin' the heads 'of the pins *64;- to connect them with said pins. By-this mode of connecting the'v tab-folders with the pins they are held firmly but at the same time they are readily removed when itis necessary 'to change from one size to another.` The pins l-f-lare inserted in horizontal perforations in'. turrets 965-, These turrets are connected by means of pivots -66`-? with slides G7- which have square perforations through them for the squarebars -68- on which the slides are mounted and secured by suitable set-screws. The vbars 68 68' are passed through oppositely i placed head-blocks '-69-69-'an`d these head blocks have square studs projecting from their fender sides.' which are inserted -in sockets in 'the' slides -70; The-slides are connected with the plate L byxdovetailed projections on'their-nnder sides inserted indove-'tailed grooves in the platefsothat the slides can u move in and out or on radial lines to va limited extent for the purpose of moving the tab-folders against the tabs to tuck them in against and' afiixing thenito the ends ol' the box. 'The turrets 6.5- are connected4 with the lower ends of the -spiral springs -7 1.- coiled around theirpivots 66, the upper ends oi'said .springs being connected'with-tension regulating: nuts -72 on the pivots -G(-. These springs are for the purpose of holding thc tab-iolders in their` correct posure against-the tucked in tabs to cause them to be come aixed to the endseffthe box.

The slides GTi-'are adjustable on the bars v 68'- "to adaptrthe tab-folders on each bar to he removed towards andfrom each .other to adjustthem in connection with-tucking in the folds of the boxes of. different lengths. Set'screws are provided to lasten 'the slides to the. bars and retain vthem in the position'to which they are adjusted.; The pins "-64-7 are also movable placed inthe o peningrin the plate L with itsridge resting on the ridge yo-e ol theplatefon which it oscillates-the ridge n nserving as la track." This .ring is'flush with the-topxad bottom of the plate L ,and on opposite sides studs -8l-.Sljproject from -l its under side and are inserted in the inner ends ol the linlrs -7S`78, the links thus connecting` the. slides M70-70` with. the ring.' V,The ring` is also pivotally connectedwlth a forked bar h82- (see 3), the forked outer end` ot'which embraces the vertical shalt ,U above'thecam 83 Athe lace of which bears against a roller *l-"o'nthe fork. The ring is also connected with one ehdof a spiral spring 8.5-, thc opposite end of which is connected with the under side of thefpl-ate r." Bymeans of the cam.- 83- the ring' is turned in the 'direction oi its arrow (see Fig. 3) and the return motion' is producedby thespring -85I au oscillating links -78'-7S- cause the slides -70-'T0- to move Ain and out andthereby give a reciprocating motion to the tab-folders Whichare thus caused to tuck in the tabs and aixthcm to'the ends of the box. The f 'turrets have' rearwardly projecting armsy -TS-R-which are'provided ,at the outer ends with.'

pendent eyes *d6-f. Straps or bridges --87-87- which span the slides '-70-70'- are riveted Fn* bolted to the plate L; izo-these straps or bridges square studs v- -S8-88 are fastened andon these studs ixedarrns -89 -89- are-n'lounted.` The outer ends f these arms are-provided with swiveled eycs.-90- .Rods

By this motion 'oy' swinging them away from the ends of the-box at u the end of their motionor before they reach the ends oi the tabs, andthis is accomplished by connecting" lthe turret arms 8584. with the fixed arms 894.'

The rods v-91-V it will be observedare atfobtuse f O angles to the lines `,o movement of the tab-folders; A

hence, when'tlielatter move a certain distance, 'de-v `termined by the set of the arms, the outer ends of. the rodsllear against the eyes in the ends of the arms Vcaused 'to turn on their pivots and thus swing the pins -64- outward and carry the ends -62- of the taliiolders away from the tucked in tabs before they reachv the edge'sthereof and take up the glue.

' covering mechanism-' The mechanism for this 80' purposers located in gallery O and it .comprises the elastic rollers -92-92-A sleeved onshafts -9393- (see Figs.` 1 and 3), each of which is j ournaled in bearings 'in the en ds of bolts 9i- 94- inserted in the bifurcate'd ends 9 5-954- of the bars -96-964-- connected with 85 I* the upturned ends of the adjustable plates -,-97`-v97` '-.r 'secured to the plate L by set-screws passeddown through slots in the adjustable plates and tapped into'plate L. y y

The bolts are secured in the bifurcated ends ofthe rods are coiled around the bolts between one side the orlc" and the collars '-99-'99-- These springs hold the bolts in their proper positions but allow them to move back or yield more or less 'when lateral pressure is appli-ed' "I to the rollers. Over the rollers there are guard plates '95 10G-100% having their edges curved l downwar'df slightly and projected a short distance inward beyonc'l` the faces oi 'the rollers.

A The several parts of the machine having been now described and their operation in performing their 'several functions explained, the cordinate actions of the several parts and the general operation of the machine in covering a box will now be described.

When the machine is ready for starting, the low point -w of the cam 10- is in Contact with the'roller as shown by Fig. 6. ,The operator places a cover 224- (Sheet V11) on thestable -35- and centers it there by means of the gages Z Zso that the bottom part within the dotted'lines, which covers the bottom of the box' lies on the table and the side parts -22 and end parts 226- outside the dotted lines that cover the sides and ends of the box and the tabs or projections 227 that are tucked in and folded against the ends of the box project outside the edges of the table. The operator next places the uncovered box .-228- on the plunger 34- grasping it by one corner at the top and holds it thereon while the plunger moves down to the support and carrier. This can be done without putting made shalloWer than the box and the edges of the latter project above the top of the plunger the latter does not prevent grasping of the box by its top edge or edges. The treadle is now pressed down whereby the pin -2lis released and, entering one of the holes in the spurwheels couples the sleeve to the counter-shaft and starts the cam -l0-.

From w to w the rise of the cam -lO- is abrupt and thc plunger is moved down rapidly to the table and support and the box is carried by it and its bottom pressed down on the cover on the table where it is held between the plunger and the table during` its subsequent movement. The cam continuing to rotate passes the roller from the point in to wz thcreby'moving the plunger down and depressing the'table, and the box and cover are carried down between the side covering rollers -55-55- which turn up and alix the sides 225-225- of the cover tothe sides ot' the box as shown by Fig. ll. The plunger and table continue their downward movement and the ends of the cover are lnought in line with the tab-folders -59-59-60-60.

Fromm/11 to w3 there is a dead part 'ot' the cam and the downward movement of the plunger and table is arrested while the tab-folders move laterally against the ends` ot the box and atlix themthereto. To accomplish moving the i'ork 824 thereby turning the ring -79- which causes the links -.-78-78- to move the slides` --70- inward. The tab-olders bear against -the tabs or projections w227- ar In a or fold them inward and alli): them tothe end. tue box as shown by Fig. l2.

From di" to u# the face ot the cam rises and in passimr l'rom the former to thelatter point the plunger mm es the table or support and carrier down between the end covering-.rollers -9292- which turn up and aiix the ends 226-11 O the covers to the ends ol' the box as .shown by Fig. 13. The tucking-in of the projections or tabs and turning up oi the ends of the covers and the aftixing oi these parts to the ends ot thc box cause considerable pressiue against the ends oi the box and this has a tendency to bulge the sidcsand cause the newly affixed sides oi' the -cover to separate therefrom. l This is"prevented by the vertical plates -57-57 which support the sides ot the cover while pressure is exerted against the ends. d

From w3 to L04 the face ol th c cam rises and while this part is passing the roller the plunger and the table are moved down to the edge turners lO- and when the top edges of the box are at or just below the bottom edgesof the edge turners the point fur* oi' the cam --104v arrives at the roller d416". l

From lw" to 'ws is a dead part of the cam and the movement of the plunger is again arrested while thc edges 229- of the cover project above the edges of the box and extend above the bottom edges ol' the edge-turners and parallel thereto. When this position isreached4 the cam'---li}z'g-`- on shaft U through the connecting rod or bar turns the ring in the diret .tion ot' its arrow, thereby through the links --llfn moving the sliding plates 11G-lllM inward and by means of the connecting links the edgc-iurncrs are carried inward against the edges of the cover and .turn-them over the top edges of the box to a horizontal position where they are held by the edge turners as shown by Fig. 14. By this movement also the edge turners are brought together end to end and form the rectangular side supporting frame the dimensions of ',which, that is to say its length and Width are slightly than the internal length and width of thc box so that the trame can enter thel box when the latter is raised upward. The position ot' this frame with respect to the box is indicated by dotted lines Fig. 4. This action ol' the edge rui-ners takes placewhile the cam is moving post the rollers 46" or from zu* to '105, and iis-soon as th(I edge iin-ners pass the edges of the box and their ends moet and form the rectangular' .side-supporting immo the hollow or low point of the cam from 105 to 113 passes to the roller 4G-- and the under side ot` the cam flange -45- bearing down on the rollers 4S-mpull thc slotted bar downward to the extent ot' thidcpression in the camy between wf' ,and fw, thereby moving the plunger up to the extent ol' the down- Athrow o the cam. At the same time the 'compres-sod air in the cylinder under the piston exerts :i lifting force on the piston that causes the table to move upA ward simultaneously with'thc plunger so that the relative positions of the plunger and table remain tho same. l"urthcrmorc the action oi the r-omprissed ai'r being more''prompt7 quicker and certain than [be action of the camT the plunger is lifted or moved up ,ing

lBU

bends of the box and inside of the same.

by the use oi compressed air to compensate for the delay or slowness of the action of the cam and cou uterwcight arising i rom friction7 inertia, lost motion dac. When this upward movement takes place the sides and ends oi tbe box are coincident. with a vertical line between the edgeV turners and the presser blocks -l51-; hence by this movement thetop edges oi the lslotted bar, actingv through the connecting rods 7136* cranks -138- rock levers -134- vertical rods -l32- bell-crank levers l30 and links ,-128, throws the movable jaws inward thereby carrying the presser is stripped from the plunger and ejected, and the plunbloclrs -151- against the exterior of the sides and ends of the box near' the top and clamping the said sides and ends and turned in edges of the cover against the faces of the edgefturners forming the rectangular" side supporting frame, thereby atlixing the turned in edges to the inside surfaces of thc sides and ends of the box. When this is accomplished the roller passes out of the hollow`--l47- of the damand the. cam acting against the roller F144- on the' slotted bar moves the bar back, thereby reversing the above motions and throwing the movable jaws with the presser blocks backward and away from the sides 0i thebox. This backward motion of the mechanism is `facilitated and made more prompt by the spiral springs -148- which make up for l'ost motion &c., in the connecting rods and the mechanism by which they are operated and other causes that retard the motion o the mechanism, it being necessary, on account of the downward motion of the plunger, which takes place at this time, that the box ashould be I released irom the edge turuers and presser blocks as quickly and promptlyas possible,

With the afiixing of the edges inside of the box the covering of the box is completed and it only remains to strip the box from the plunger and eject it from the machine. i l From the point w the cam face rise-s abruptly and when this point passes'the roller the plunger again descends and deprcsses the table, carrying the box d'own.until the top edges thereof are just below the shoulders 185- of the strippers --l8l-, whereupon these strippers are moved towards the center of the machine until the shoulders project over the tops of the side edges of the box; this occurs about the time the highest point of the cam at w7 reaches the roller 46- when the plunger is at iis lowest position. The strippers now more in until the shoulders are immediately over thc lop edges of the box whereupon the highest point oi the cani passes the roller H46*- and the low par: from wT to Lr bears against the roller and the plunger moves upward. and as the edges of the box are caught under the shoulders ol' the strippers the plunger is wit hdruwn from the box and returns to its normal position above the leed table o1' the machine while the box remains onthe top of the tableA At the same moment. the notch e203 in the wheel 202- reaches esserev the end of the arm and the spring --2()4-- pulls the arm over thereby'throwing the cushioned head -l92--- of the ejector against the yend ol the box and ejects the box from the table into the chute M206 which delivers it to a receiving table (not shown).

When the plunger began its upward movement and the box was stripped oft, the high part of the cam ]5- passed the roller in, the fork -104- and thereupon the springs r-l07 reacted and turned the'ring L10I- the reverse of itslarrow, whereby through the ,link connections the sliding plates -110-111--were vcaused to move bpclr and carry the edge turners to.

their' normal position out of the way of therascending plunger; also causing the strippers to move back to their normal position. The support and carrier being this time at-its lowest point andthe piston at the bottom of the air cylinder the valve -ltlis closed so that the suction opposes the counter-weight and the support and carrier remains stationary until the box ger has moved upward more or less on its return to its normal position. 'At this stage cam 170- reaches the lever, and valve 16,l# is opened partly permitting the air to enter the cylinder under the piston' and by reducing the suction allowing the counter- .veight to move the support upward but not so rapidly as to overtake the plunger nor before the strippers are moved back out of its way. In its-upward course it strikes against the ejector but the latter having a jointed stem swings upward out oi its 'way and when it` has passed drops down again to its normal horizontal position. When the support and carrier reaches the level of the end covering rollers, or say about 2/3 of its upward or return travel cam -170 passes the roller on the arm A `thereby reduced the air passing into the cylinder is partly cut off and the suction being increased, the movement of the support and carrier is checked or slowed down. But as the cam rises toward its rear side the valve is gradually opened wider and the movement of the support and carrier is correspondingly accelerated, but continues under the control of the valve so that it arrives at'its normal position without shock or jar and at the same moment cam -.l7lpasses the roller and the valve is closed by the springon the valve rod cutting off the entrance of air whereby the support and carrier is cushioned by the suction oi the air against the piston. At or about the time of the arrival o the support and carrier at its normal position, the inclined face ot' the' pin -21- comes in contact with the in- V clined face of the treadle arm and the pin being drawn I baclr'thelsleeve is uncoupled from the spur wheel and the operationof the machine thereby stopped.
